oddly enough i checked out the accord today. everyone is indeed raving over it. mechanically and dynamically i could understand but the interior of the car is not as nice in person as it is in pictures. I think the Mazda 6 is nicer and that ain't saying much. I did test drive a six speed maxima again.....love that engine but maybe its worth it to wait till 2004. ok....sorry to have interrupted the topic...bye bye

"Apparently if the argument for OHV is so strong then why is GM itself being contradictory." I'm not saying DOHC's are a good design! I'm saying the Hondas and Mitsubishis and such with em don't make any torque! I mean, look at the early 90's ZR-1 Corvette: one of the Fastest Corvettes ever produced, and it was a GM DOHC V8 engine, top notch. DOHC definately is awesome, just not always, and in comparison to everything... "seems to be occuring with quite high frequency." It is a very rare problem. "Do you think the S/C version is MORE likely to develop this problem sooner because of the high pressures it generates during blower activation? Seems it might." The S/C 3800 is completely different up top, and doesn't use the same top end.

I posted this same message in the Buick Regal forum (I own a '98 GS and wife owns a '00 GSE): I see where the '04 Pontiac GTP engine is now rated at 260 HP instead of 240, with 280 ft-lbs of torque. Has anyone heard if the '04 Regal GS will be getting this same improved version of the S/C 3800? I wonder though why the engine torque stayed at 280 ft-lbs, instead of increasing to say, 300 ft-lbs? They must have improved the exhaust flow and/or are using a smaller pulley to get 20 more HP. Does anyone have an answer to my question?

It's a new engine (well, sort of!). It's the Series III 3800, instead of the Series II 3800 in the new GTPs. There is a new higher efficiency supercharger, throttle by wire, and a few other features. The HP goes up as you see and the torque probably does to cause they're related (it's probably underrated), but the tranny is rated at 280 ft/lbs of torque, so instead of designing a new tranny, they just "didn't" raise the torque numbers. The new engine should rock!

"It is a very rare problem." please review drivinisfun's post #11498 on the chevrolet impala topic in sedans.....even the owners admit it is an issue.

It is a very rare problem! It happens in about 2% of cars.. if that.

Regfootball, SOME owners (who have had the problem) claim it is a very common problem. NOT "THE" owners. I am an owner. I also post over there. My 2000 LS has 113,000 miles on it, with only a headlight switch and brakes replaced, the latter at over 80,000 miles! Please don't put words in "the owners" mouths. If ONE Impala owner steals a dog, that does not make me a dognapper. And one or two or even six dozen people on the internet in what is often a complaints forum posting about a problem does not necessarily mean the problem is widespread.

Thanks for the info about the new 3800 Series III. Why in hell didn't Chevy install this same engine in the '04 Impala SS and Monte Carlo SS? Could it be some GM exec (Bob Lutz?) didn't want the '04 SS Chevys competeting with the '04 GTP? I sometimes wonder what their marketing people are thinking!

i'd bet its more than 2%...... considering how it is a design flaw it may happen to all who own that engine. hell, if my father in law in the town of a thousand says his mechanic told him he's already fixed three of them before his, and he's not even a dealer mechanic........ heck just go to google.com and type in "3800 manifold problem".....tell me its rare then.
#135 of 233 by atbear Mar 02, 2003 (4:39 pm)
Yeah, we don't like that it didn't get the Series III, but the reason is the same that it didn't get the S/C 3800 til now-- they didn't want to step on Buick and Pontiac's toes. reg, the manifold problem is rare, and it doesn't affect a high percentage of 3800s.
